Attention: Your JBL CINEMA SB450 comes with subwoofer
already paired from the factory, please refer to the subwoofer
connection section of this owner’s manual only if you are
experiencing no audio output from your subwoofer after
connecting it to the power.
Wireless Pairing:
Press this button to initiate wireless pairing
between the subwoofer and the soundbar. The LED lights
white continuously when the subwoofer is on and linked to the
soundbar. The LED slowly flashes white when the subwoofer is
on and the wireless link is not established between the subwoofer
and the soundbar. The LED rapidly flashes white during the
wireless pairing process.
Phase Control:
This switch determines whether the subwoofer
driver’s piston-like action moves in and out in phase with the
speakers in the soundbar. If the subwoofer were to play out of
phase with the soundbar speakers, some of the sound waves
produced by the subwoofer or soundbar could be canceled,
reducing bass performance and sonic impact. This phenomenon
depends in part on the relative placement of the speakers in
the room. See the “Subwoofer Phase Switch” section for more
information.
Crossover:
This knob adjusts the subwoofer’s cutoff between
40Hz and 200Hz.The higher you set the Cutoff control, the higher
in frequency the subwoofer will operate and the more its bass will
“overlap” that of the soundbar. This adjustment helps achieve a
smooth transition of bass frequencies between the subwoofer
and the soundbar for a variety of different rooms and subwoofer
locations. See the “Subwoofer Crossover Control” section for
more information.
Power Cord Connector
Connect the included power cord here
and into an active, unswitched AC outlet. See Power Connections
for more information.
IMPORTANT: Do not connect the power cord to an
AC outlet until you have made and verified all other
connections.
SOUNDBAR PLACEMENT
PLACING THE SOUNDBAR ON A TABLE
If your TV is placed on a table, you can place the soundbar on
the table directly in front of the TV stand, centered with the TV
screen. As long as the surface of the table is flat, the soundbar will
rest on its metal feet. Set the soundbar’s EQ switch in the “Table”
position. See Soundbar Rear-Panel Controls and Connections.
WALL-MOUNTING THE SOUNDBAR
If your TV is attached to a wall, you can use the included wall-
mount bracket to mount the soundbar on the wall directly below
the TV screen.
1. Determine the location for the soundbar on the wall. Make
sure that the top of the soundbar will not block your view of
the TV screen when it is mounted on the wall.
2. Hold the bracket against the wall as a template and mark the
locations of the soundbar wall-mount bracket holes on the
wall. The three holes should be evenly spaced 7-1/16” (18cm)
apart, and the bracket slots are designed to accept 4mm
screws. Make sure that the holes are at the same height. See
the illustration below.
Mark Three Bracket Hole Locations
7-1/16" (18cm) Apart
3. Making sure that the bracket’s flat side is against the wall,
attach the wall-mount bracket to the wall at the locations
you marked, using hardware that is appropriate for the wall’s
construction and materials. Note that the soundbar weighs
7.5 lb (3.4kg). Be sure to use hardware that can support this
weight.
After reading the Connections section, connect all cables to the
soundbar.
